Using Traditional Psychometric Methodologies and the Rasch Model in Designing a Test.
Crislip, Marian A.; Chin-Chance, Selvin
This paper discusses the use of two theories of item analysis and test construction, their strengths and weaknesses, and applications to the design of the Hawaii State Test of Essential Competencies (HSTEC). Traditional analyses of the data collected from the HSTEC field test were viewed from the perspectives of item difficulty levels and item discrimination indices. Both classical test theory and item response theory analyses were applied to the HSTEC items. It appears that using both approaches during the test development process will make the resulting instrument more likely to provide data that are reliable for making inferences that are valid. The value that each perspective contributed toward test development also supports the idea that no one method should be used in developing tools to measure latent traits. Whether or not the item tests what is valued should be the primary emphasis in examining test items. (SLD)
